Objective To analyze the correlative factors of peptic ulcer recurrence in the elderly. Methods From January to December 2009,169 elderly patients (≥ 60 years old)with peptic ulcer delected by edoscopy were enrolled,whose treatment and usage of medication were analyzed.Data of treatment and recurrence in 3-year follow-up were recorded.Mann-Whitney rank sum test and Logistic regression analysis were performed to analyze the correlated factors.Results The potential risk factors associated with recurrence of peptic ulcer in the elderly were screened and analyzed by single factor analysis,and ulcer size, ulcer location, concomitant usage of drugs, smoking and condition of Helicobacterpylori (H .pylori )infection at the end of follow-up were found to be correlated with recurrence of peptic ulcer in the elderly.After adjusting age and gender,the potential risk factors were analyzed by a Logistic stepwise regression model.Smoking (OR = 1 .788,P = 0.001 ),combined medication (OR=6.202,P =0.015 ),ulcer size (OR =2.697,P =0.032 )and condition of H .pylori infection at the end of follow-up (OR=43.784,P =0.007)were found to be correlated with recurrence of peptic ulcer in the elderly.Conclusion Smoking,combined medication,ulcer size and condition of H .pylori infection at the end of follow-up have an impact on peptic ulcer recurrence in the elderly.

Objective To investigate the relationship between carotid artery plaque formation and blood pressure(BP),pulse pressure(PP),mean blood pressure(MBP) in elderly men.Methods A total of 1461elderly men were divided into carotid artery plaque group(n =1012)and non-carotid artery plaque group(n =449) according to vascular ultrasound examination.Systolic blood pressure(SBP) and diastolic blood pressure(DBP) were recorded by 24-hour ambulatory blood pressure monitoring(ABPM),at the same time pulse pressure (PP)and mean arterial blood pressure(MBP)were calculated.The relationship between carotid artery plaque formation and SBP,DBP,PP,MBP were analyzed.Results The age in carotid artery plaque group was significantly higher than that in non-carotid artery plaque group[(80.5±5.4) years old vs(77.3±5.9) years old,t =-4.233,P ＜ 0.01];The levels of SBP,PP and M BP in artery plaque group were significantly higher than those in non-carotid artery plaque group[SBP:(132.2±17.0) mm Hg vs(127.5±16.0) mm Hg,t =-4.893,P ＜ 0.001; PP:(60.8±13.4) mm Hg vs(55.9±12.5) mm Hg,t =-5.021,P ＜0.001) ;MBP:(92.6±10.3)mm Hg vs(91.0±9.9)mm Hg,t =-3.897,P ＜ 0.01].The incidence of carotid artery plaque was closely related to age(OR =1.061,P =0.0001),myocardial infarction(OR =1.896,P =0.0135),hypertension grades(OR =1.177,P =0.0019),high cholesterol(OR =1.353,P =0.0335),reduced systolic function(OR =2.466,P =0.0001),lower extremity arterial plaque(OR =5.453,P =0.0001).Conclusion In elderly men,formation of the carotid artery plaque is closely related to increased SBP,PP and MBP,but independent to DBP.

Objective , To investigate the influence of blood pressure variability on cerebral infarction in older men. Methods Ambulatory blood pressure was measured in 1527 elderly men ( older than 65 yrs) with atherosclerosis. All cases were divided into 2 groups: Six hundred and seven patients with cerebral infarction ( group A)and 920 patients without cerebral infarction ( group B). Smooth curve method was used to analyze each patient's ambulatory blood pressure data and the trend of each patient's blood pressure curve was portrayed. The differences between the actual blood pressure and the blood pressure on the curve was defined as blood pressure variability,and the blood pressure variability between the 2 groups was compared. Results The systolic blood pressure variability in 24 hours in group A was significantly higher than that in group B( [8.4'±2. 2]mm Hg vs [ 8.0 ± 2. 0 ] mm Hg, P ＜ 0. 01 ), especially for the systolic blood pressure variability in daytime( [ 8. 2 ± 2. 2 ] mm Hg vs [ 7. 8 ± 2. 1 ] mm Hg, P ＜ 0. 01 ). However, the systolic blood pressure variability at night was not significantly different between the 2 groups( [ 8.9 ± 3. 9 ] mm Hg vs [ 8. 7 ± 3.7 ] mm Hg,P ＞ 0. 05 ). There were no significant difference between the diastolic blood pressure of 24 hours( [5. 5 ± 3.8 ] mm Hg vs [5.5 ± 1.5 ]mm Hg,P ＞0. 05),during daytime([5.4 ± 1.5]mm Hg vs [5.3 ± 1.4] mm Hg,P ＞0.05)and nighttime ( [ 6. 1 ± 2.7 ] mm Hg vs [ 6. 1 ± 2. 6 ] mm Hg, P ＞ 0. 05 ). Conclusion In elderly men with atherosclerosis,cerebral infarction was closely related to systolic blood pressure variability,but independent of nighttime systolic blood pressure and diastolic blood pressure variability.

ObjectiveThe study aimed to quantitatively evaluate the short-term effects of ultrafine particles （UFPs） exposure on the occurrence and mortality of cardio-cerebrovascular diseases. MethodsThe number of daily cases of cardio-cerebrovascular events， including stroke and acute myocardial infarction， and mortality of cardio-cerebrovascular diseases， daily concentrations of air pollutants and weather conditions in Minhang， Shanghai from January 1， 2016 to December 31， 2018 were collected. Associations between UFPs and the number of daily cases and deaths were analyzed by the general additive Poisson regression model with the control of meteorological variables， day-of-the-week effects and time trends. Increased percentages of the number of daily cases and deaths and 95%CI were used to indicate the short-term effects of UFPs. ResultsDuring the study period， in the single-pollutant model， an increase of 2022 particles/cm³ showed significant effects with 5.01%（95%CI： 1.22%‒8.94%）and 6.05%（95%CI： 1.53%‒10.80%）increments in the percentages of the number of daily cases and deaths respectively. After adjusting other pollutants in the two-pollutant model， statistically significant associations were also observed. ConclusionUFPs exposure has acute impacts on the occurrence and mortality of cardio-cerebrovascular diseases.

Accumulating studies suggest that, as the subway is one of the important means of transport in cities, airborne microorganisms in its system have potential effects on human health, but previous studies have mainly focused on some foreign cities. We reviewed the spatio-temporal distribution characteristics of airborne microorganisms in subway stations in different cities, including diurnal, weekly, and seasonal variations, and the distribution of microorganisms in different regions of the world. The factors affecting airborne microorganisms, such as human activities, temperature and humidity, ventilation, and particulate matter, were presented. The potential health effects were described. Although there was no significant risk of infection from using subway, many pathogens do exist in the air. The influence of microorganisms in subway air on health has become a public health problem that cannot be ignored.

OBJECTIVE: To investigate the current status of quality of working life( QWL) among medical staffs in Minhang District,Shanghai City,and to explore the relationship between QWL and occupational stress. METHODS: A stratified sampling method was used to select 522 medical staffs in Minhang District,Shanghai City. The QWL and occupational stress were assessed using the Quality of Working Life Scale and the Effort-Reward Imbalance Questionnaire,respectively.RESULTS: The total score of QWL of medical staffs was( 97. 7 ± 13. 8),and the detection rate of high occupational stress was34. 7%( 181/522). The total QWL score of medical workers in the high occupational stress group was lower than that in the low occupational stress group( P < 0. 01). The results of multivariable logistic regression analysis showed that occupational stress and average weekly working time were risk factors of reduction in QWL( P < 0. 01). CONCLUSION: Occupational stress is the influencing factor of QWL. The increased occupational stress may reduce the QWL of medical personnel.

ObjectiveTo analyze the changing trend of cerebrovascular disease burden in Minhang District of Shanghai from 1996 to 2021， and to provide scientific evidence for government to formulate targeted cerebrovascular disease prevention and control strategies. MethodsMortality， years of life lost（YLL）， years of lived with disability（YLD） and disability⁃adjusted life years（DALY） were used to evaluate the burden of cerebrovascular diseases in Minhang District. Joinpoint linear regression was used to analyze the trend of disease burden. ResultsFrom 1996 to 2021， the YLL rate of cerebrovascular diseases in Minhang District showed a downward trend （whole population： APC=-1.69%， t=-6.9， P<0.05）， The YLD rate of cerebrovascular diseases showed a slow upward trend （whole population： APC=1.17%， t=3.5， P<0.05）， The DALY rate of cerebrovascular diseases showed a downward trend， and fluctuated since 2003 （whole population： APC= -1.43%， t=-5.6， P<0.05）. The YLL rate of cerebrovascular diseases in men was higher than that in women， and the YLD rate of cerebrovascular diseases in women was higher than that in men. After 2014， the DALY of cerebrovascular diseases in men was higher than that in women. With the increase of age， the burden of cerebrovascular diseases increased， and the burden of disease increased significantly in the age group above 70. ConclusionThe burden of cerebrovascular diseases in Minhang District is at a high level， and there are differences in age， gender and other aspects. Measures such as screening， intervention and rehabilitation need to be improved to reduce disability and premature death caused by cerebrovascular diseases and to reduce the burden of cerebrovascular diseases on individuals， families and society.
